Enable Transparent Huge Pages

The Fastcapa probe performs its own memory management by leveraging Transparent Huge
Pages (THP). In Linux, you can use the Transparent Huge Pages to enable either dynamically or
automatically upon startup. Hortonworks recommends that these be allocated on boot to increase

The total number of huge pages should be distributed fairly evenly across each
non-uniform memory access (NUMA) node. In the following example, a total of 16 requested
THPs are distributed as 8 to each of 2 NUMA nodes:
